| Footage description: | Noel Carr introduces the programme. Carr uses a diagram to explain one of the early classic experiments on bacteria in which a new strain, a recombinant of two others, was bred. Carr lists the three methods by which recombination occurs in bacteria. He goes on to describe one such method, transformation. Carr uses diagrams and electron micrographs to illustrate his points. Carr goes on to describe a second method, transfer of DNA by bacteria phage. Diagrams illustrate the points. Carr describes the third method for recombination, conjugation. Micrographs and diagrams illustrate points made. With the aid of an animation Carr explains how actual genetic information is transferred through high frequency recombination. Carr goes on to explain how the discovery that the bacterial genome was circular was made. Gene map for E. coli shown. Electron micrograph of Cavin's classic experiment which confirmed the circularity of the bacterial genome :with commentary by Carr. Jean Holley demonstrates some of the crucial steps and techniques associated with the student home experiment on the fungus Schizophyllum Commune. |
